and with the casing 3 inclosing; the motor gear ng and operative parts of the machine for driving the cutter chainand propelling the machine, it all being mounted upon a is adapted to slide along the mine hottom While cutting a kerf in the coal. driving sprocket driven through the transmission gearing (not shown) of the machine is adapted to engageacahle chain 6 and both propel and guide the machine in making the lateral out, as well-as in making the starta explained in the aforesaid Mitchell patent.

\Vhile the invention is shown as applied to a machine of the described type, it will be evident that as to manyessential ,features it may he usefully employed with mining' machines Widely differing construe tional details and mode of operation from the one hereinahove referred to.

Referring to the constructional features of the truck illustrated in Figs. 1 to 4, inclusive, the same is mounted upon two pairs of truck wheels101carried by axles 11, the latter journaled in the hrackets12attached to the fixed or under portion of thetruch frame. The latter isherein formed loythe two longitudinal angle irons 13 and con-F nected at 'tl'ie'ifront by the transverse bridgingpiece 15 and at the rear by the similar piece 16 to form a rigid rectangular frame. li'itermediate the hridgingpieces l5 and 16 the angle ironsll-i and 14 are also connected by and rigidly attachedto a bridging piece 17 which serves as a support on which the upper or swiveled portion of the truck frame may he turned. Theupper portion of the truck frame is composed primarily of the longitudinal angle irons 18 and 19 9 connected by the transverseplates 9.0. and 21 which latter rest upon and have sliding contact with thehridging pieces 15 and 16, re-

spectively, of the lower truck frame. Inter mediatethe transverse plates 20 and 21 the upper truck frame has fixedly secured there- I l. x130 :rcircular plate or turntable 29; which is mining machine for which the swiveled to turn 'upon the correspondingly shaped hearing plate 23 represented by the" intermediate bridging-member1710i the lower ira me member,- the turntable 22 havprior patent to Mitchell No. 656,414.

In virtueof its swiveled support upon the lower frame member the upper frame member which carries the mining machine may be turned to present its longitudinal axis of alinement 5 with that of the lower frame member or at right angles thereto or at any intermediate position.

The mining machine as indicated in Figs. 5 and 6 when loaded on a truck is adapted to 10 rest upon the angle irons 18 and 19, but may be discharged from the truck at any desired angular position with relation thereto, being guided in a right line direction in its discharge movement by the upright sides of the angle irons between which the frame and shoe of the machine is adapted to slide and be guided. end of the swivel frame is preferably provided with flared ends 26-and 27, respectively, formed by flaring out the angle irons- 18 and 19 and these ends preferably project beyond the stationary truck frame.

The stationary or lower frame of the truck is herein shown provided with supporting devices located at the rear of the machine whereby the truck may be propelled under the power of the machine and also for supporting an electric cable reel. For this purpose the angle irons 13 and 14 have secured thereto rearwardly and upwardly extending prolongations 28 and 29 connect-'- ed bv the cross plate 30 and carrying the supporting arms 31 and 32 for supporting a cable rail. .To propel the truck there is 35 also provided on the frame formed by the rearwardly extending members 28 and 29 a truck driving gear 33 journaled about an upright axis and adapted to drive the truck through appropriate connections; For this purpose the gear 33 turns the beveled gear 34, the latten meshing with the gear 35. and the latter in turn drives the transverse shaft 36 through the beveled gears 37 and 38. At theside of the truck the shaft 30 is provided witha sprocket wheel-37 which, turns the rear axle of the truck through the sprocket chain 38 and sprocket wheel 39. The. forward truck axle is driven from the rear axle by means of the connecting sprocket chain 40. The truck driving gear 33 is so disposed upon the frame that when the mining machine is loaded on the frame and in its rearmost position it is caused to mesh with the truck driving pinion 41car ried by the machine and driven from the motor on the machine through appropriate transmission devices (not shown). The truck wheels 10 are adapted to travel upon a suitable trackway 42 laid upon the bottom of themine. I v With the described form of truck the mining machine after having been loaded on to the truck with the upper frame in alinement with the lower frame, 2'. e. lengthwise the trackway, may be propelled under the The forward or discharge power of the mining machine to the room or other location in the mine where the cutting is to be performed. When the desired position is reached, the upper frame may be turned about its swiveled support to discharge the machine laterally at any required angle. The machine is particularly adapted for bench. work where the cut is to be made upon a bench already formed. When brought to the side of a bench such as'is indicated at 43 in Figs. 5 and 6 and properly angled the sumping or starting out upon the bench may be commenced directly from the truck itself by suitably fixing or anchoring the forward end of the guiding and feeding chain 6 as is indicated in'Fig. 5. The truck, therefore, not only serves a function as a conveying device for the machine, but also acts as' a starting frame .whlch may be angled as required and from which the machine may be discharged at a be made-and that extensive deviations may be had without departing from the spirit of the invention.
